Story

Meet Sabrina, a gentle 6-year-old Mastiff mix who’s in need of a special forever home. Sabrina is living with mast cell tumors (MCT) due to cancer and is currently on medication to keep her as comfortable as possible. She requires a loving home that is prepared to offer her hospice care and a peaceful environment. Sabrina can be shy with new people and may give a warning growl or snap if approached when she’s not ready. However, once she builds trust, she becomes deeply affectionate and very attached to her people. She gets along well with mellow dogs and will thrive in a calm household where she can feel safe and loved. If you have a compassionate heart and are ready to provide a supportive and caring home for a special dog like Sabrina, you’ll find a loyal and loving companion in her.

Story

Meet Stimpy, the perfect family dog Stimpy is a 6-month-old Mastiff/Catahoula Leopard Dog mix with the softest heart and sweetest soul. He’s truly not a fearful pup — while he was a bit hesitant about leaving the house or getting into the car at first, he now walks right out and hops in with no problem. He’s been enjoying off-leash trails, meeting other dogs and people, and he’s friendly with everyone. He loves social time and is clearly comfortable exploring new environments. At home, his playful personality really shines — including his signature move: a full-send “Superman jump” off the couch that never fails to make his people laugh (even if we never quite catch it on camera!). Stimpy is gentle and especially tender with kids, melting into cuddles the moment he feels safe. Overall, he’s a sweet, loving, and friendly pup who is still learning appropriate play manners. He’s hopeful, curious, and ready to bring joy, laughter, and cuddles to his forever family If you’re looking for a loving, gentle, big-dog puppy with a heart of gold, Stimpy is your guy.

Story

This pups adoption fee has been partially sponsored by All Aboard or an All Aboard partner! The new adoption fee is reflected on the profile. IMPORTANT NOTE REGARDING THIS DOG: Ombre can be easily startled by new people and things. He is occasionally slower to meeting new people, especially men, and other dogs. Ombre has the potential to get overwhelmed easily and can resource guard. Ombre needs an adopter who is patient and willing to continue his training. Ombre is big guy with a lot of love to give! He came to us with a few quirks that his foster has been helping him work through and he is constantly making progress! He does need an experienced adopter who will be dedicated to continued positive reinforcement training and ongoing socialization. He has come a long way since his arrival in January 2023 and needs the perfect partner in crime to help him continue making progress! Ombre can be a bit skittish with new sounds or unexpected movements and can resource guard at times. He is occasionally slow to warm up to new men and other dogs, but not consistently! He can get overwhelmed in new high-activity environments, so continued socialization is a must. Ombre is very loving and curious, and acts like he is his foster's shadow. This loving boy is a classic case of a dog who is worth the effort! With the right, experienced adopter who is committed to setting him up for success through continued training and socialization, Ombre will absolutely blossom into his adopter's most dedicated friend! He is house and kennel trained. Playgroup - https://youtube.com/shorts/Brmr_wwiRKs ADOPTION FEE: $75 We are a foster-based rescue and do not generally have pups available to meet at our office except during adoption events on Saturdays. Interested in this pup? The first step is to complete our online application by clicking the "Apply for Adoption" button. Please note that we are only able to finalize adoptions at events for approved adopters. The earlier you apply, the better as it takes time to review and approve applications. We host adoption events almost every Saturday from 11:00am to 2:00pm at Petco in Fort Collins (2211 S College Ave. STE 200, Fort Collins, CO 80525)! Check our Instagram and/or Facebook page for info on where we will be hosting adoptions this weekend! All Aboard Animal Rescue saves dogs and puppies from high-kill shelters in other states. These pups are brought to Colorado, where they are required to be spayed or neutered - breaking the cycle of unwanted litters of puppies who end up as strays! Please consider supporting us in this mission by adopting, fostering, volunteering, or donating.
